The findings come as world leaders met at COP27 in Egypt to discuss the climate crisis. The research team, including the University of Exeter, the University of East Anglia (UEA), CICERO and Ludwig-Maximilian-University Munich, welcomed this slow-down, but said it was "far from the emissions decrease we need". The average rise peaked at plus three per cent per year during the 2000s, while growth in the last decade has been about plus 0.5 per cent per year. This year's carbon budget shows that the long-term rate of increasing fossil emissions has slowed. However, climate change reduced the uptake of CO2 by the ocean and land sinks by an estimated four per cent and 17 per cent, respectively, over the 2012-2021 decade. Land and oceans, which absorb and store carbon, continue to take up around half of the CO2 emissions. To reach zero CO2 emissions by 2050 would now require a decrease of about 1.4 GtCO2 each year, comparable to the observed fall in 2020 emissions resulting from Covid-19 lockdowns, highlighting the scale of the action required. The remaining carbon budget for a 50 per cent likelihood to limit global warming to 1.5 degrees has reduced to 380 GtCO2 (exceeded after nine years if emissions remain at 2022 levels) and 1230 GtCO2 to limit to two degrees (30 years at 2022 emissions levels). The 2022 picture among major emitters is mixed: Emissions are projected to fall in China (0.9 per cent) and the EU (0.8 per cent), and increase in the US (1.5 per cent) and India (six per cent), with a 1.7 per cent rise in the rest of the world combined. The growth in oil emissions can be largely explained by the delayed rebound of international aviation following the pandemic restrictions. Projected emissions from coal and oil are above their 2021 levels, with oil being the largest contributor to total emissions growth. Emissions from land-use change (such as deforestation) are projected to be 3.9 GtCO2 in 2022. This is fuelled by fossil CO2 emissions which are projected to rise one per cent compared to 2021, reaching 36.6 GtCO2 - slightly above the 2019 pre-Covid 19 levels. The new report projects total global CO2 emissions of 40.6 billion tonnes (GtCO2) in 2022. If current emissions levels persist, there is now a 50 per cent chance that global warming of 1.5 degrees Celsius will be exceeded in nine years. New Delhi, Nov 11 (IANS): With emissions projected to increase in India by six per cent, global carbon emissions in 2022 remain at record levels - with no sign of the decrease that is urgently needed to limit warming to 1.5 degrees Celsius, according to the Global Carbon Project science team.
